Abstract

A display device may include a substrate, a plasmonic aluminum reflector layer over the substrate, and a conducting oxide layer over the plasmonic aluminum reflector layer. The display device may have a circular polarizer over the conducting oxide layer and configured to receive incident visible radiation. The incident visible radiation may cause plasmon resonance within the plasmonic aluminum reflector layer. The display device may include a circuit configured to apply a voltage between the conducting oxide layer and the plasmonic aluminum reflector layer to cause the plasmonic aluminum reflector layer to selectively reflect the incident visible radiation based on the voltage.
